Power Supply

The power supply consists of the power supply bay and one power supply module. A second power supply module can be purchased to provide a redundant, 1+1 system. With either configuration, the power supply provides 350 watts of power and is designed to minimise EMI.

The power supply operates within the following voltage ranges and is rated as follows:

The power subsystem supports the implementation of remote management features, including remote enable that permits power to be activated from a variety of sources.

System Cooling

The chassis includes two 80-mm non-hot-swappable system fans for cooling the processor(s), hard drives, and add-in cards. A third fan may be added in the center position to provide cooling redundancy for system components. The system fans are mounted in a fan assembly located in the middle of the chassis to pull cooling air through the chassis. The power supply contains a single fan for cooling.

Security

To help prevent unauthorised access to the system’s peripherals and control panel, an optional key-locked front bezel can be used. The chassis also includes a preinstalled intrusion switch that can be monitored by server management software. When the cover is opened, a switch located on the front panel board transmits a signal to the Baseboard Management Controller (BMC) on the server board. Through server management software, the system can be programmed to respond to an intrusion by powering down or by locking the keyboard. At the chassis level a variety of security options are provided.

Rack and Cabinet Mounting Options

The SX220 chassis was designed to support 19” wide by up to 30” deep server cabinets. The chassis comes equipped with a relay rack or cabinet mount kit that can be configured to support front-mount or mid-mount 2-post racks and 4-post cabinets. Viglen also provides an optional sliding rail kit that is used to mount the chassis into a standard (19” by up to 30” deep) EIS 310D compatible server cabinet.

For mounting in a regular server cabinet, the front mount brackets are attached to the front of the chassis, and a set of rear support brackets are attached to the back end of the cabinet. This evenly distributes the server to prevent the mounting rails on the cabinet from bending. Caution should be used in using the front mount-only option. Even though the rail mount kit hardware was designed to support the weight

10

Viglen SX220 User Guide

of the system, some 2-post relay racks may not, causing the racks to fail. Only use relay racks that are specifically designed to support the weight and stresses of a 2- post front-mount only chassis.

Optional Peripherals

The SX220 server chassis provides six hard drive bays at the front of the chassis. An optional seventh drive may be used in the flex bay. All hard drive bays may be populated with a tray mounted 3½” hard disk drive. If a configuration requires the use of a floppy disk drive and CDROM drive Floppy/CDROM module may be used in place of the seventh hard drive in the flex bay. A tape drive bay is located below the flex bay.

Hot-Swappable Hard Disk Drives

The SX220 server chassis can support up to seven tray-mounted SCA2, 3½” x 1” and Ultra2/Ultra160 hard disk drives.

A major feature of the hot-swap bay is the backplane which powers down a drive when a failure is detected and reported to the SCSI bus. When a new drive is inserted, the power control waits a short time for the drive to become fully seated and then applies power to the drive. The backplane provides signals to the control panel to indicate failure status for each drive in the bay.

The chassis ships with six drive carriers for mounting the separately purchased hard drives. For information on how to install these drives, refer to page 43.

Flex Bay

For those configurations that require a floppy drive and CD-ROM drive, the seventh drive bay or “Flex Bay” will be configured as a peripheral bay by inserting the Floppy/CDROM module. The Floppy/CDROM module is a 3½” floppy drive and a ½” (12.7mm) slim-line CDROM drive mounted as a single unit in the peripheral bay. A release latch allows for tool-less removal from the front of the server, however, the Floppy/CDROM Module is not hot swappable. The system must be powered down before the module is inserted or removed from the flex bay.

If the Flex Bay is used to house a SCA2 hard disk drive the bay will be hotswappable the same as the six other standard bays.

Processor

The SCB2 motherboard accommodates one or two Intel Pentium III processors with 512k cache in the FC-PGA2 package. This processor uses the 0.13 micron technology and offers advanced performance. The processor external interface operates at a maximum of 133 MHz.

Memory

The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64bit main memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). Memory is two-way interleaved and partitioned in three banks. You may install a minimum of 128 MB (64MB x 2) and as much as 6 GB.

The controller automatically detects, sizes, and initialises the memory array, depending on the type, size, and speed of the installed DIMMs, and reports memory size and allocation to the server via configuration registers.

NOTE: Use DIMMs that have been tested for compatibility with the server board. Contact your sales representative or dealer for a current list of approved memory modules

The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the other end of the cable must also be terminated. LVD devices generally do not have termination built-in and need to have a termination source provided. Non-LVD devices generally are terminated through a jumper or resistor pack on the device itself.

IDE Controller

The system includes a single channel enhanced IDE 32 bit interface controller for intelligent disk drives with disk controller electronics onboard. The controller has a connector located on the system board that supports a master and a slave device. The device controls:

•PIO and DMA transfer modes

•DMA-33 capable

•Mode 4 timings

•Transfer rates up to 33 MB/s

•Buffering for PCI/IDE burst transfers

•Master/slave IDE mode

•Up to two devices.

16

Viglen SX220 User Guide

Network Controller

NOTE: To ensure EMC product regulation compliance, the system must be used with a shielded LAN cable.

•Chained memory structure similar to the 82559, 82558, 82557 and 82596

•Full duplex support at both 10 Mbps and 100 Mbps operation

•Low power +3.3 V device

•IP checksum off-loading

The SX220 server NIC 1 can be used as both a network interface and server management interface.

NIC Connector and Status LEDs

The 82550 controller drives LEDs on the network interface connector that indicates link/activity on the LAN and 10or 100-Mbps operation. The green LED indicates network connection when on and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit.

Network Teaming Features

NOTE: Using both on-board NICs in a team does not allow the use of NIC 1 for server management access. To support both network teaming features and server management features, a third NIC must be added and teamed to NIC 2.

•Adaptive Load Balancing (ALB) - creates a team of 2 - 8 adapters to increase transmission throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.

•Fast EtherChannel (FEC) or Intel® Link Aggregation - creates a team of up to 8 adapters to increase transmission and reception throughput. Also includes AFT. Requires a FEC-enabled switch.

To set up an option, read the instructions in the Windows NT 4.0 or NetWare 4.1x readme files.

General Configuration Notes

1.Windows NT versions prior to 4.0 do not support Adapter Teaming options.

2.Adapter Teaming options require NT 4.0 with Service Pack 4.0 or Service Pack 3.0 and the Windows Hot Fix.

3.In Windows NT, teaming options cannot be implemented on adapters that have been configured for VLANs. NetWare can support teaming options and VLANs on the same adapters.

Adapter Fault Tolerance

Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the reliability of server connections. AFT gives you the ability to set up link recovery to the server adapter in case of a cable, port, or network interface card failure. By assigning two server adapters as a team, AFT enables you to maintain uninterrupted network performance.

AFT is implemented with two server adapters: a primary adapter and a backup, or secondary, adapter. During normal operation, the backup will have transmit disabled. If the link to the primary adapter fails, the link to the backup adapter automatically takes over.

Preferred Primary Adapter

With multiple adapters installed, you can specify one as the Preferred Primary adapter. For example if you have a server with a PRO/1000 server adapter as the primary adapter and a PRO/100+ adapter as the secondary, you could configure the PRO/1000 server adapter to be the preferred primary. In this scenario, if the PRO/1000 server adapter fails, the PRO/100+ will take over. Then when the PRO/1000 server adapter is replaced, it will automatically revert to being the primary adapter in the team.

If a Preferred Primary is not selected, PROSet will attempt to select the best adapter, based on adapter model and speed.

18

Viglen SX220 User Guide

Mixed Adapter Teaming

AFT supports up to eight server adapters per team, in any mix.

Adaptive Load Balancing

Adaptive Load Balancing (ALB) is a simple and efficient way to increase your server’s transmit throughput. With ALB you group server adapters in teams to provide an increased transmit rate (up to 8 Gbps) using a maximum of eight adapters. The ALB software continuously analyses transmit loading on each adapter and balances the rate across the adapters as needed. Adapter teams configured for ALB also provide the benefits of AFT. Receive rates remain at 100 Mbps or 1 Gbps depending on the primary adapter’s capability.

To use ALB, you must have 2-8 server adapters installed in your server or workstation and linked to the same network switch.

Cisco Fast EtherChannel

Fast EtherChannel (FEC) is a performance technology developed by Cisco to increase your server’s throughput. Unlike ALB, FEC can be configured to increase both transmission and reception channels between your server and switch. FEC works only with FEC-enabled switches, such as the Catalyst 5000 series. With FEC, as you add adapters to your server, you can group them in teams to provide up to 18 Gbps at full duplex, with a maximum of 8 server adapters. The FEC software continuously analyses loading on each adapter and balances network traffic across the adapters as needed. Adapter teams configured for FEC also provide the benefits of AFT.

To use FEC, you must have 2, 4, or 8 server adapters installed in your server and linked to the same FEC-enabled Cisco switch.

Keyboard and Mouse

The keyboard/mouse controller is PS/2-compatible. If specified through the System Setup Utility (SSU), the server may be locked automatically if there is no keyboard or mouse activity for a predefined length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse do not respond until the previously stored password is entered. A Y-cable can be used if both a PS/2 mouse and keyboard are required at the same time.

RJ-45 Serial Port

The rear RJ-45 serial port is a fully functional COM port that supports any standard serial device and provides support for serial concentrators, which typically support RJ45 serial connectors. For server applications that use a serial concentrator to access the server management features of the baseboard, a standard 8-pin CAT-5 cable from the serial concentrator is plugged directly into the rear RJ45 serial port.

Viglen SX220 User Guide

19

The 8 pins of the RJ45 connector can be configured to match either of two pin-out standards used by serial port concentrators. To accommodate either standard, the J6A2 jumper block located directly behind the rear RJ45 serial port must be jumpered appropriately according to which standard is desired.

NOTE: By default, as configured in the factory, the SCB2 baseboard will have the rear RJ45 serial port configured to support a DSR signal.

For serial concentrators that require a DCD signal, the J6A2 jumper block must be configured as follows: The DCD jumper in position 2 and 3 and the DSR jumper in position 2 and 3. Pin 1 on the jumper is denoted by an arrow directly next to the jumper block. See Figure 9 on page 129 for the jumper block pin-out of this configuration.

Figure 6: Jumper Block Pin-out

For serial concentrators that require a DSR signal, the J6A2 jumper block must be configured as follows: The DSR jumper in position 1 and 2 and the DCD jumper in position 1 and 2. An arrow directly next to the jumper block denotes pin 1 on the jumper. See Figure 7.

Figure 7: Jumper Clock Pin-out

For those server applications that require a DB9 type of serial connector, an 8-pin RJ45-to-DB9 adapter must be used. The following table defines the pin-out required for the adapter to provide RS232 support.

Viglen SX220 User Guide

NOTE: The RJ45-to-DB9 adapter should match the configuration of the serial device used. One of two pin-out configurations are used depending on whether the serial device requires a DSR or DCD signal. The final adapter configuration should also match the desired pin-out of the RJ45 connector, as it can also be configured to support either DSR or DCD.

For systems configured with both a front and rear RJ45 serial connectors, the adapters used for the rear port cannot be used with the front port, as the pin-out for both RJ45 ports are different. For example, modem applications typically use DCD. In this case the user would use a DCD-configured adapter and set the jumper block as shown in Figure 6.

ACPI

The SCB2 server motherboard supports the Advanced Configuration and Power Interface (ACPI) as defined by the ACPI 1.0 and PC97 specifications. An ACPI aware operating system can put the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. However, the power supply will still be on and the processors will still be dissipating some power, so the power supply fans will still run.

The boards sleep states s0, s1, s4, and s5:

•s0: Normal running state.

•s1: Processor sleep state. No context will be lost in this state and the processor caches will maintain coherency.

•s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing the power button or other wakeup event will restore the system state from the disk and resume normal operation. This assumes that no hardware changes have been made to the system while it was off.

•s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No context is saved by the OS or hardware.

CAUTION!

The system is off only when the AC power is disconnected.

Security

Intrusion Switch Monitoring

To help prevent unauthorised entry or use of the server, Intel® Server Control server management software monitors the chassis intrusion switch if one is installed. Opening an access cover will transmit an alarm signal to the server board, where BMC firmware and server management software process the signal. The system can

Viglen SX220 User Guide

21

be configured through ISC to respond to an intrusion a number of ways, including powering down or locking the keyboard.

Software Locks

The BIOS Setup and the System Setup Utility (SSU) provide a number of security features to prevent unauthorised or accidental access to the system. Once the security measures are enabled, you can access the system only after you enter the correct password(s). For example:

•Enable the keyboard lockout timer so that the server requires a password to reactivate the keyboard and mouse after a specified time out period.1 to 120 minutes.

•Set and enable a supervisor password.

•Set and enable a user password.

•Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset and power switches.

•Activate a hot key combination to enter secure mode quickly.

•Disable writing to the diskette drive when secure mode is set.

•Disable access to the boot sector of the operating system hard disk drive.

Using Passwords

You can set the user password, the supervisor password, or both passwords. If only the user password is set, you:

•Must enter the user password to enter BIOS Setup or the SSU.

•Must enter the user password to boot the server if Password on Boot is enabled in either the BIOS Setup or SSU.

•Must enter the user password to exit secure mode.

If only the supervisor password is set, you:

•Must enter the supervisor password to enter BIOS Setup or the SSU.

•Must enter the supervisor password to boot the server if Password on Boot is enabled in either the BIOS Setup or SSU.

•Must enter the supervisor password to exit secure mode.

If both passwords are set, you:

22

Viglen SX220 User Guide

•May enter the user password to enter BIOS Setup or the SSU. However, you will not be able to change many of the options.

•Must enter the supervisor password if you want to enter BIOS Setup or the SSU and have access to all of the options.

•May enter either password to boot the server if Password on Boot is enabled in either the BIOS Setup or SSU.

•May enter either password to exit secure mode.

Secure Mode

Configure and enable the secure boot mode by using the SSU. When secure mode is in effect:

•You can boot the server and the operating system will run, but you must enter the user password to use the keyboard or mouse.

•You cannot turn off system power or reset the server from the front panel

switches.

Secure mode has no effect on functions enabled via remote server management or power control via the watchdog timer.

Taking the server out of secure mode does not change the state of system power. That is, if you press and release the power switch while secure mode is in effect, the system will not be powered off when secure mode is later removed. However, if the front panel power switch remains depressed when secure mode is removed, the server will be powered off.

Summary of Software Security Features

The table below lists the software security features and describes what protection each offers. In general, to enable or set the features listed here, you must run the SSU and go to the Security Subsystem Group, menu. The table also refers to other SSU menus and to the Setup utility.
